• What is the cause and solution for SAP error message /PF1/PE_PP_BASIS027 - Start of non-parallel processing ?

  The SAP error message /PF1/PE_PP_BASIS027 indicating "Start of non-parallel processing" typically arises in the context of background processing or job scheduling in SAP. This message suggests that the system is unable to initiate parallel processing for a specific task or job, which can lead to performance issues or delays in processing.
  Causes:
  
  System Configuration: The SAP system may not be configured to allow parallel processing for certain jobs or tasks.
  Resource Limitations: There may be insufficient system resources (CPU, memory) available to execute jobs in parallel.
  Job Dependencies: The job may have dependencies that prevent it from running in parallel with other jobs.
  Locking Issues: If a job is trying to access a resource that is currently locked by another process, it may fall back to non-parallel processing.
  Job Priority: The job may have a lower priority compared to other jobs, causing it to run sequentially.
  
  Solutions:
  
  Check Job Configuration: Review the job configuration in transaction SM37 (Job Monitoring) to ensure that it is set up for parallel processing.
  Adjust System Parameters: If necessary, adjust the system parameters related to parallel processing. This can be done in transaction RZ10 or RZ11 depending on the parameter.
  Resource Allocation: Ensure that the system has adequate resources (CPU, memory) to handle parallel processing. This may involve scaling up the hardware or optimizing existing resources.
  Review Job Dependencies: Check for any dependencies that may be preventing the job from running in parallel. You can do this in the job definition.
  Monitor Locks: Use transaction SM12 to check for any locks that may be affecting the job. If locks are found, investigate and resolve them.
  Increase Job Priority: If applicable, consider increasing the priority of the job to allow it to run in parallel with other jobs.
